| ''Comparing shapes of engel curves'' |
| ( 2009, Vol. 29 No.2 ) |
| |
| |
| We measure how different the shapes of Engel curves are across 59 commodity groups. The same analysis is carried out for their derivatives and variances. While Engel curves possess a relatively homogeneous shape, significantly more heterogeneity is present in derivatives and when particular sub-classes of income are considered. |
